Group stages miraculous revival of once-toxic lake — here's how they accomplished the unthinkable
The Uru Uru Team, launched in 2019 by Indigenous youth, is bringing hope to the once-stunning Lake Uru Uru. The Bolivian lake used to be home to hundreds of flamingos. But those numbers are dwindling because of pollution and environmental degradation.
Dayana Blanco Quiroga, co-founder of the Uru Uru Team, told the Equator Initiative — which organizes a prize recognizing "outstanding community efforts to reduce poverty through the conservation and sustainable use of biodiversity" — that the nearby San José mine empties its pipelines into the lake. Plastic litter has also accumulated, leaching toxins into the waters as it slowly degrades.
"We have decided to come together again as a community and do something for our lake," said Blanco Quiroga, an Aymara woman from the community of Vito.
The team's solution is a native aquatic plant called totora, traditionally used to feed livestock, for rafts, and for other handicrafts.
Unfortunately, totora has also been on the decline, and the smell of the polluted lake presented a challenge. But the team has been able to find and cultivate the resilient plants and fashion them, along with recycled waste from the lake, into floating rafts.
"Our elders gave some ideas for a good floating raft design. The Indigenous women and sisters from our community decided to found the community garden, which generates income to buy workwear and be equipped and protected to plant Totoras," Blanco Quiroga told The Convention on Wetlands, adding that her team also protects the floating rafts from vandalism.
Totora naturally absorbs heavy minerals and other pollutants — a concept known as phytoremediation — and the project has reduced lake pollution by 30%, per the Equator Initiative.
In 2023, the Uru Uru Team was honored with the Equator Prize after demonstrating "an effective model to ensure the well-being of an Indigenous community, preserve their knowledge and cultural identity, while curbing lake pollution to protect biodiversity."
Blanco Quiroga hopes her team's work will help restore Lake Uru Uru to a pristine state.

"My mother is an example of resilience and perseverance, and she motivated me to dream higher and believe that the work of restoration we are doing in the Uru Uru Lake will leave a spark of hope to the next generations that they can feel change is possible if we find the harmony with the Mother Earth," she told The Convention on Wetlands.

Can Africa's great nomadic people save their way of life?
'If rainy season comes and we have grass and water, I'm happy,' says Fulani herder Alhajji Soh, 25, pictured in the rural community of Déali, Senegal, where rainfall has decreased dramatically. 'Some years we don't have grass and water … at those times I'm unhappy.' Photographs by Robin Hammond Near the southern edge of the Sahara desert, millions of people in some 20 West and Central African countries share a way of life. Year after year, they take part in the ancient practice of nomadic pastoralism, herding livestock across increasingly hot, arid lands of the Sahel region in search of fresh grasslands and accessible water as the seasons change. From the western coast of Senegal to the eastern shorelines of Sudan, herders follow different migratory routes that can cover hundreds of miles. Most of these pastoralists share another important distinction: They are Fulani, an Indigenous people who have a broad cultural identity shaped by such traditional journeys. These groups are vast and varied, and many are traveling in new directions. The Fulani, a predominantly Muslim collection of Indigenous communities spread across nearly two dozen Central and West African countries, are connected by pastoral traditions that stretch back centuries. In northern Cameroon, teenagers (from left) Fadimatou Moussa, Hawaou Hamadou, and Amin Moussa belong to the Mbororo people and take part in annual migrations. Ousmanou Hamadou, 67, and Hamadou Adamou, 51, tend to their goats, sheep, donkeys, and cattle in Cameroon. In fact, the majority of these predominantly Muslim people today are no longer herders. In recent generations many took up farming or settled in towns and cities to follow different prospects to provide for themselves and their families. In Guinea, the Fulani who migrated to the Fouta Djallon mountainous region now grow crops and allow their livestock to roam free. In Sierra Leone, many Fulani have become entrepreneurs who wield influence over the direction of trade and politics. In Nigeria, where the population has grown dramatically, Fulani herders now face increased competition for land and resources. Here, pastoralists lead their cattle through arid lands during the dry season, which in recent years has lasted longer due to climate change. Because Fulani herders are often in transition, they have historically encountered issues accessing and managing the lands they've traversed for generations. Yet despite Fulani people being minorities in almost all the countries where they have settled, several strong leaders have emerged. In recent decades, at least five Fulani presidents have served in African nations. Across the Chad Basin—a landlocked region that includes parts of Chad, Niger, Nigeria, and Cameroon—conflict orchestrated by the jihadist group Boko Haram has disrupted the livelihoods of many Fulani, displacing communities of herders and farmers that have been forced to settle in camps like this one called Taal. Violence accompanying territorial disputes is just one of the many challenges that confront the Fulani. After fleeing violence in Burkina Faso, Jajo Jallo, 49, and his family became refugees in Ghana. Adam Gaya, nine, along with his donkey named Bako, is shown in the village of Fadouk in Niger. On the most basic level, 'Fulani' has become an umbrella term that encompasses many different groups of people, explains Hindou Oumarou Ibrahim, a Fulani Mbororo woman and a knowledge holder among her community. She compares those groups to branches on the Fulani tree. 'In West Africa, you have Futa Toro [and] Fouta Djallon,' says Ibrahim, who is a National Geographic Explorer and president of the Peul Indigenous Women and Peoples Association of Chad. 'And then in our area of Central Africa we have some Mbororo'—which is her own branch of peoples. Within the branches there are many different communities. But the majority still feel a strong connection to the land, she says, and their ancestral way of life. At the same time, those who carry on the traditional practice encounter new threats from climate change and regional disputes along their pathways, including occasional aggression from landowners. Some of the more recent conflict may be fueled by an unfounded assertion among some governments and non-Fulani communities that the Fulani are disproportionately joining jihadist groups. The reality is that herders heavily contribute to the region's economy and have a long history of peaceful trade with farmers and business owners. For years, these Mbororo people typically migrated between Nigeria and Cameroon, but as the land they traversed has fallen into private ownership, their traditional routes have become dangerous. Now they travel only within Cameroon where some swaths of open grassland still offer a welcoming corridor. Their journey continues to be an arduous one as temperatures soar in the region. While Fulani may live off the land, they also help replenish it. As these pastoralists travel, Ibrahim points out, their livestock leave behind manure that enriches the soil with nutrients, creating more fertile land. They also trim trees along their routes, strengthening branches that encourage growth and protect against brush fires. Pastoralism is the most adapted livelihood to the Sahel ecosystem, Ibrahim says. (Meet the woman who is inspiring a new future for Africa's nomadic herders.) To gain deeper insight into these often misunderstood communities, photographer and National Geographic Explorer Robin Hammond chronicled their travels over a six-year period. In this story, he shares rare images that speak to their vibrancy and to the enduring hardships they face. 'Fulani culture is amazing and unique, but it's important not to romanticize it,' says Hammond. 'Many herders are just struggling to survive.' A version of this story appears in the July 2025 issue of National Geographic magazine. An Explorer since 2019 and Barcelona-based photographer, Robin Hammond documented the traditions and challenges of nomadic Fulani people in communities across Chad, Niger, Cameroon, Ghana, Senegal, and elsewhere. The nonprofit National Geographic Society, committed to illuminating and protecting the wonder of our world, funded Explorer Robin Hammond's work. Learn more about the Society's support of Explorers.

Indigenous communities in Canada evacuated as wildfires rage
STORY: "Excuse me... [STARTS CRYING]" :: June 4, 2025 It's hard for Joseph Garry to talk about the fires ravaging Manitoba's remote northern communities. :: Sandra Yaworski :: Flin Flon, Canada :: May 28, 2025 Scores of wildfires have swept across Canada since the start of May, forcing more than 30,000 people to evacuate in three provinces. Although Indigenous people make up only around 5% of Canada's population, they are among the most affected by this year's wildfires. GARRY: "To tell you the truth [RUBBING TEARS AWAY FROM EYES] it's, it's scary. Not for myself, but for everybody else." The 63-year-old Garry fled from Mathias Colomb Cree Nation, also known as Pukatawagan, on a helicopter in late May with only a few sets of clothes. "...we left everything behind." :: Sandra Yaworski The fire evacuation effort is Manitoba's largest-ever. :: Selena Castel :: June 1, 2025 :: Pukatawagan, Canada Videos shared by residents with Reuters showed military and civilian helicopters buzzing back and forth over the remote community of roughly 3,000 people. The helicopters landed on the school field as thick smoke enveloped the area and flames inched nearer. Dozens of people huddled inside a Chinook military helicopter, including Selena Castel, a councilor for Pukatawagan. "Very challenging, I'll tell you that right now. It was like nobody, nobody didn't want to hear us out when we pressed the emergency button." // "And it was very scary. Especially when you see big flames coming up from the other side of the, you know, close to the airport." :: Chief David Monias of Pimicikamak Cree Nation via Facebook :: May 28, 2025 :: Jenpeg, Canada Indigenous leaders in Manitoba have criticized both federal and provincial governments for inadequate communication and delays during the wildfire crisis. Indigenous Services Canada, which managed the evacuation, said emergency response is a shared responsibility and first response is generally up to local authorities. :: Chief David Monias of Pimicikamak Cree Nation via Facebook :: May 29, 2025 :: Cross Lake, Canada Manitoba's government said in an email that smoky conditions near Pukatawagan early in the emergency response prevented water bombers from providing vital air support. While early evacuees took shelter in Winnipeg, Castel and Garry are among the roughly 2,000 people from Manitoba now staying in hotels in the Niagara Falls area in Ontario. A date to return home is uncertain.

Woodstock, N.B, writer wins Writers' Federation of New Brunswick nonfiction award
Keith Helmuth 'honoured' to be recognized for Tappan Adney book Woodstock's Keith Helmuth was all smiles as he accepted the Writers' Federation of New Brunswick Award for Nonfiction for 'Tappan Adney: From Birchbark Canoes to Indigenous Rights.' The book, published by Goose Lane Editions and Chapel Street Editions in October 2024, details the life and legacy of Tappan Adney, who is credited with saving the art of birchbark canoe construction through his writing and building miniature replicas. 'I felt the Tappan Adney biography had a good chance of winning, but when I heard my name called out, I had a deep sense of satisfaction that all the years of work that had gone into making this an important and well-written book by a number of people was being fully recognized,' said Helmuth, in an email to the River Valley Sun. He wrote the book with Ted Behne, James Wheaton, Daryl Hunter, and Nicholas Smith. The book accounts for Tappan Adney's multifaceted impact on history and culture. Adney is an artist, writer, and advocate for Indigenous culture, with a fascination with birchbark canoes, which started after meeting Peter Jo, a Wəlastəkwi Elder-craftsman, in 1887. That meeting sparked a lifelong dedication to documenting Indigenous canoe designs and preserving the Wəlastəkwey language and traditions. His contributions extended beyond canoe craftsmanship; he was also a journalist, illustrator, and defender of Indigenous rights, introducing the 1725 Peace and Friendship Treaty into Canadian legal discussions. By winning the award, Helmuth hopes the book will become better known nationally and even internationally, expecting more people to appreciate Adney's vital role in preserving cultural heritage and defending Indigenous rights. 'It was the goal of everyone who worked on this book to make Adney and his achievements more well-known and appreciated,' said Helmuth The Carleton County Historical Society has a room dedicated to Adney in the Connell House Museum.
